What is a Pregnant Horse Called?

When it comes to horses, there are many fascinating aspects to explore. One such aspect is the terminology used to describe different stages of a horse’s life. In this article, we will delve into the topic of what a pregnant horse is called. We will provide a comprehensive explanation, covering the terminology, gestation period, signs of pregnancy, and the care required for a pregnant horse. So, let’s get started!

Understanding the Terminology

Before we dive into the details, it’s important to understand the terminology associated with a pregnant horse. A pregnant horse is commonly referred to as a mare in foal. The term “mare” refers to a female horse, while “foal” is the term used for a young horse, typically under one year of age. So, when a mare is pregnant, she is referred to as a mare in foal.

Gestation Period of a Horse

The gestation period of a horse refers to the length of time between conception and birth. It is essential to know the average gestation period of a horse to determine when the foal is due and to monitor the mare’s health during pregnancy. The gestation period for a horse typically ranges from 320 to 370 days, with an average of around 340 days. However, it’s important to note that individual variations can occur, and the actual duration may vary slightly.

Signs of Pregnancy in Horses

Identifying the signs of pregnancy in horses is crucial for horse owners and breeders. Here are some common signs that indicate a mare is pregnant:

  • Cessation of Estrus: One of the primary signs of pregnancy in a mare is the cessation of estrus, also known as heat. A pregnant mare will no longer exhibit signs of being in heat.
  • Changes in Behavior: Pregnant mares may display changes in behavior, such as increased docility or irritability.
  • Enlarged Abdomen: As the pregnancy progresses, the mare’s abdomen will gradually enlarge. This is one of the most visible signs of pregnancy.
  • Development of Mammary Glands: The mare’s mammary glands will undergo changes and become more prominent as the pregnancy advances.
  • Fetal Movement: In the later stages of pregnancy, the foal’s movement can be felt by placing a hand on the mare’s abdomen.

Caring for a Pregnant Horse

Proper care and management are essential to ensure the health and well-being of a pregnant horse. Here are some key aspects to consider when caring for a pregnant mare:


Adequate nutrition is crucial for a pregnant horse to support the growth and development of the foal. The mare’s diet should be well-balanced and provide the necessary nutrients, including:

  • Protein: Protein is essential for tissue growth and milk production. High-quality forage and protein-rich concentrates should be included in the mare’s diet.
  • Minerals and Vitamins: A balanced mineral and vitamin supplement should be provided to meet the mare’s requirements during pregnancy.
  • Energy: The mare’s energy needs will increase as the pregnancy progresses. This can be met through increased forage or the addition of energy-dense concentrates.

Veterinary Care

Regular veterinary care is crucial throughout the mare’s pregnancy. Here are some important aspects of veterinary care for a pregnant horse:

  • Pre-Breeding Examination: Before breeding, the mare should undergo a thorough examination by a veterinarian to ensure she is in good reproductive health.
  • Ultrasound and Hormone Monitoring: Regular ultrasound examinations and hormone monitoring can help confirm pregnancy and monitor the foal’s development.
  • Vaccinations and Deworming: The mare should be kept up to date on vaccinations and deworming to protect her and the developing foal.
  • Preparation for Foaling: As the due date approaches, the mare should be closely monitored, and preparations should be made for foaling, including creating a clean and safe foaling environment.

Exercise and Rest

Proper exercise and rest are essential for a pregnant horse. Regular exercise helps maintain muscle tone and overall fitness, while adequate rest allows the mare to conserve energy. However, it’s important to avoid excessive exercise or strenuous activities that may put unnecessary stress on the mare or the developing foal.

Environmental Considerations

The mare’s environment plays a significant role in her well-being during pregnancy. Here are some environmental considerations:

  • Stable and Pasture: The mare should have access to a clean, well-ventilated stable and a suitable pasture for grazing. The environment should be free from hazards that may pose a risk to the mare or the foal.
  • Temperature and Weather: Extreme temperatures or severe weather conditions can impact the mare’s comfort and health. Adequate shelter should be provided to protect the mare from harsh weather conditions.


In conclusion, a pregnant horse is called a mare in foal. Understanding the terminology and the signs of pregnancy is essential for horse owners and breeders. Proper care, including nutrition, veterinary care, exercise, and a suitable environment, is crucial to ensure the health and well-being of both the mare and the developing foal. By providing the necessary care and attention, horse owners can support a successful pregnancy and look forward to the arrival of a healthy foal.
